Hydroxyethyl methyl methacrylate

Hydroxyethyl methyl Methacrylate n A monomer that polymerizes to a hydrophilic polymer that is rigid when dry but when saturated with water becomes a soft, clear material (Hydron ). Applications include masonry coatings, soft contact lens, and other biomedical devices. 

A typical process for the preparation of an acryUc solution terpolymer of composition 27.5% 2-ethyIhexyl acrylate—41.3% methyl methacrylate—31.2% hydroxyethyl methacrylate begins with the following charges ... 

Styrene monomer was also copolymerized with a series of functional monomers by using a single-step dispersion copolymerization procedure carried out in ethanol as the dispersion medium by using azobisizobu-tyronitrile and polyvinylpyrollidone as the initiator and the stabilizer, respectively [84]. The comonomers were methyl methacrylate, hydroxyethyl acrylate, metha-crylic acid, acrylamide, allyltrietoxyl silane, vinyl poly-dimethylsiloxane, vinylsilacrown, and dimethylamino-... 

Hydroxy-containing polymers such as poly(methyl-methacrylate-co-hydroxyethyl methacrylate) [65,66] or secondary cellulose acetate [67,68] were used for this purpose. Vanadium (V) 8-hydroxy quinoline-hydroxy-ethyl methacrylate adduct, prepared by condensation of the latter with a VOQ2OH complex, is polymerized to...

Materials and Purifications. 2-Methyl pentene-1 (Aldrich) was distilled under normal pressure at 62°C after refluxing for one hour 1n the presence of A1L1H.. Methyl methacrylate and para-methyl styrene (Aldrich) were distilled under reduced pressure at about 60°C the purified monomers were sealed and stored 1n refrigerator before use. The compressed gas, sulfur dioxide (Matheson), was led through a P208 tower before Introduced Into reaction system. Hydroxyethyl acrylate (Aldrich) was used for polymerization without further purification. 

Similar increases in k with ultrasonic intensity have been found for other polymers such as polystyrene [44], poly(methyl methacrylate) [45], poly(dimethylsiloxane) [46], poly(ethyleneoxide), hydroxyethyl cellulose, poly(vinyl acetate), poly(acrylamide)...

Cross-linked copolymers of hydroxyethyl methacrylate and methyl methacrylate are slightly swollen by water and are used as soft contact lenses. 

Copolymers of acrylonitrile and methyl acrylate and terpolymers of acrylonitrile, styrene, and methyl methacrylate are used as bamer polymers. Acrylonitrile copolymers and multipolymers containing butyl acrylate, ethyl aciylate, 2-ethylhexyl acrylate, hydroxyethyl acrylate, methyl methaciylate. vinyl acetate, vinyl ethers, and vinylidene chlonde are also used in bamer films, laminates, and coatings. Environmentally degradable polymers useful in packaging are prepared from polymerization of acrylonitrile with styrene and methyl vinyl ketone.
